Description Claire E 2024-10-18 21:42:47 UTC 
Application: plasmashell (6.2.1)

ApplicationNotResponding [ANR]: false
Qt Version: 6.8.0
Frameworks Version: 6.7.0
Operating System: Linux 6.11.3-arch1-1 x86_64
Windowing System: Wayland
Distribution: "Arch Linux"
DrKonqi: 6.2.1 [CoredumpBackend]

-- Information about the crash:
Clean install of Arch Linux on my desktop, no odd settings. I installed the dolphin package from arch repos alongside other KDE software and vesktop-bin and spotify from the AUR using yay. On the second or third time I launched it, it crashed and plasmashell did as well.

The reporter is unsure if this crash is reproducible.
